Description

[Detailed description of the invention] [Industrial application field] The present invention has a harvested grain culm in the center of the front plate of a handling chamber that is equipped with a handling barrel that rotates around a horizontal axis and a concave located below the handling barrel. In addition to connecting a feeding feeder, a discharge port is provided on both lateral sides of the rear side plate, and the processed material supplied from the feeder is rotated once from the bottom of the handling cylinder along the rotation direction of the handling cylinder to be discharged from both sides. This invention relates to a whole-culm loading type combine harvester configured to disperse and guide the culm to the exit.

[Conventional technology]

In the case of such a full-culm input type combine harvester, for example, as shown in Japanese Utility Model Application Publication No. 153941/1983,
After handling and processing the harvested grain culm introduced into the handling chamber from the feeder in the lower side of the handling barrel and in the center area of the concave, it is rotated once along the rotation of the handling barrel and distributed to the left and right, and then for the second round. The paddy is handled again under the handling barrel and on both sides of the concave, and the paddy is filtered and the remaining residue is distributed and guided to both discharge ports of the rear plate. Receptacle teeth were implanted along the entire length and width of the concave to assist the handling action of the handling teeth that span the entire circumference and width of the body.

[Problem that the invention attempts to solve]

However, the combine harvester having the above-described structure also has the following problems.

In other words, if the stem culm is difficult to cut or if the stem culm is wet, it is easy for straw to get caught in the receiving blade and remain there, and as more straw gets caught, the effective filtration of the concave becomes difficult. There were cases where the area decreased and the filtration efficiency decreased.

Therefore, in view of these circumstances, the present invention was designed to suppress the decrease in the effective filtration area of the concave caused by the straw getting caught in the receiving teeth as much as possible without impairing the handling effect applied to the harvested grain culm. The purpose of this is to enable efficient threshing.

[Means for solving problems]

The characteristic configuration of the present invention, which has been made to achieve the above object, is that receiving teeth are provided on the processing material passing path in the central area of the concave and both side areas of the front side plate, and
The two sides of the concave are configured as filter areas without receiving teeth, and the functions and effects thereof are as follows.

[Effect]

In other words, the grain culm introduced into the handling chamber from the feeder is subjected to handling action by the handling teeth and receiving teeth under the handling barrel and in the center area of the concave, and then
While rotating once in the direction along the rotation of the handling cylinder, it is distributed to the left and right and receives handling action in cooperation with the receiving teeth and handling teeth implanted in the front side plate at the position of the front side plate, and furthermore, in the second rotation, The waste is filtered under the handling barrel and on both sides of the concave, and the residue that remains unfiltered is guided to the left and right discharge ports.

[Effect of idea]

Therefore, according to the present invention, by removing the receiving teeth from both sides of the concave, the decrease in the effective filtration area due to straw getting caught in the concave is suppressed, and the receiving teeth are implanted on the front plate. This makes it possible to compensate for the decrease in handling action on both sides of the concave, and as a result, it is possible to ensure sufficient effective filtration area without impairing the handling action applied to the harvested grain culm, increasing filtration efficiency and achieving efficient threshing. It became like that.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Fig. 4, a reel 1 that raises the planted grain culm and scrapes it toward the rear of the machine, a reaping device 2 that reaps the raked grain culm, and a conveyor 3 that transports the harvested grain culm to the rear of the machine. A reaping pre-treatment device A is provided at the front, and the reaped grain culm transferred by a conveyor 3 is fed into a handling chamber 5 from a feeder 4 provided at the center of the front side, and is fed into a handling chamber 5 by a handling cylinder 6 and a concave 7. A full-culm input type combine harvester is constructed, which is equipped with a threshing section B that applies a threshing and handling action, and a sorting device C that sorts the processed material filtered from the handling chamber 5 and recovers the paddy.

Next, the threshing section B will be explained.

As shown in FIGS. 1 and 2, the feeder 4 is located in the center of the front panel 5a of the handling chamber 5, and the discharge port 8 equipped with a beater 22 is located on both sides of the rear panel 5b.
8 is provided, and handling teeth 6a are implanted over the entire width and circumference of the handling barrel, which is pivoted in the handling chamber 5, and the center area of the tooth socket 7a of the concave 7 and the front side plate. Receptacle teeth 10 are respectively implanted on two tooth receptacles 9a and 9b provided above the feeder 4 of 5a. Incidentally, the receiving teeth 10 are not implanted in both side areas of the receiving tooth stand 7a of the concave 7, but instead holes 11 are provided to promote filtration. Also, the front side plate 5a
The tooth sockets 9a and 9b are provided on the left and right sides of the front side plate 5a, and are provided in two stages, top and bottom, of which the upper socket 9a has a socket extending over the entire left and right width, and the lower socket 9b has a socket. Two rows of receiving teeth 10 are implanted only in the areas on both sides outside the feeder 4.
Further, on the upper part of the pedestals 9a and 9b, second products such as paddy with branches collected from the sorting device C are stored in a handling chamber 5.
A second reducing port 12 is provided for reducing the inside.

Therefore, the harvested grain culm fed into the handling chamber 5 from the feeder 4, together with the second crop fed from the second return port 12, is transferred to the handling teeth installed in the central area on the lower side of the handling barrel 6. 6a and the receiving tooth 10, the handling cylinder 6 rotates and is moved to the left and right by the upper guide plate 13, and when it reaches the front plate 5a, both receiving teeth Receptacle teeth 1 of stands 9a, 9b
0 and the handling teeth 6a, and in the second rotation, the handling teeth 6a implanted on both sides of the lower side of the handling barrel 6 receive a handling action, and the rearward part is stirred. The paddy and small straw waste are filtered downward. Finally, residues such as straw waste that remain unfiltered are dispersed and guided to the discharge ports 8, 8, and discharged to the straw walker 14 at the rear.
The processed material that has been handled and filtered and supplied onto the clean pan 15 is subjected to specific gravity separation by the clean pan 15, and is then oscillatedly transferred to the rear sorting device C, and the remaining material is discharged to the straw walker 14. The paddy fillets inside are filtered and supplied to the sorting device C below, while being oscillatedly transferred to the discharge port at the rear and discharged outside the machine.

As shown in FIG. 3, the sorting device C filters the processed material transferred from the clean pan 15 and the processed material filtered from the straw walker 14, and swings and transfers it to the waste dust port 16 at the rear. a grain sieve 20 which further filters and supplies the processed material filtered and supplied from the chaff sieve 17 to the first material collection section 18, swings and transfers it to the rear end, and drops and discharges it to the second material collection section 19;
It also consists of a winnow 21, etc., which sends wind for wind sorting. The front and back spacing of the front band plates 17a constituting the chaff sheave 17 is made larger than the back and forth spacing of the rear band plates 17b, so that the paddy in the lower layer that has been subjected to specific gravity sorting by the grain pan 15 is separated from the chaff sheave 17 at the front of the chaff sheave 17. In addition to quick filtration, the lower half of the front band plate 17a is bent into a dogleg shape to prevent long straw from sticking vertically. In addition, the Cleansieve 2
A grain pan section 20a is provided at the front of the chaff sieve 17 so that the processed material filtered and supplied from the front of the chaff sieve 17 can be subjected to specific gravity sorting again.
